Patent number: 11948113Abstract: One or more portions of a text corpus indicative of operational risk from a set of risk assessment documents is identified. Contextual features from the one or more portions of the text corpus are determined by applying a natural language processing (NLP) algorithm on the one or more portions. Risk identifiers are extracted based on the determined contextual features. A risk assessment software is generated based on the extracted risk identifiers and an operational risk category.Type: GrantFiled: November 22, 2017Date of Patent: April 2, 2024Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Kelly A Argyros, Donna K Byron, Lakshminarayanan Krishnamurthy, Joan W Tomlinson

Patent number: 11537821Abstract: In response to running at least one testing phrase on a previously trained text classifier and identifying a separate predicted classification label based on a score calculated for each respective at least one testing phrase, a text classifier decomposes extracted features summed in the score into word-level scores for each word in the at least one testing phrase. The text classifier assigns a separate heatmap value to each of the word-level scores, each respective separate heatmap value reflecting a weight of each word-level score. The text classifier outputs the separate predicted classification label and each separate heatmap value reflecting the weight of each word-level score for defining a heatmap identifying the contribution of each word in the at least one testing phrase to the separate predicted classification label for facilitating client evaluation of text classification anomalies.Type: GrantFiled: April 10, 2019Date of Patent: December 27, 2022Assignee: International Business Machines CorporationInventors: Ming Tan, Saloni Potdar, Lakshminarayanan Krishnamurthy

Patent number: 11501087Abstract: A knowledgebase of an expert system is populated with rules inferred from a set of business processes that govern the manner in which the business interacts with users. Each business process contains an input, an output, an action, and a set of dependency relationships that relate pairs of the input, the output, and the action. Each process's input, output, action, and dependency relationships are translated, respectively, into a subject, an object, a predicate, and a set of dependency relationships among the subject, object, and predicate, of a natural-language rule. Each rule is stored in the expert system's knowledgebase as a directed graph, and nodes representing each stored subject, object, and predicate are assigned domain classifications as a function of characteristics of the business rule. These domain classifications are represented within the knowledgebase as a set of domain classifications determined as a further function of characteristics of the business rule.Type: GrantFiled: August 30, 2019Date of Patent: November 15, 2022Assignee: International Business Machines CorporationInventors: Donna K.

Patent number: 10949454Abstract: An engagement classifier for a group chatbot is trained by leveraging the implicit dataset generated by humans engaging in both direct messages as well as group conversations. Human-to-human direct messages are used as an approximate representation of the domain knowledge and expertise of each user. The decision to engage in a group conversation is assumed to be based on that domain knowledge. The knowledge representations and instances of engagements in group conversations yields an effective set of features and labels which can be used to model the engagement decision. The same transfer learning technique is used to generate a knowledge representation for the group chatbot. Given this representation of the domain knowledge of the chatbot, the classifier can predict whether it should engage in any particular group conversation.Type: GrantFiled: October 22, 2018Date of Patent: March 16, 2021Assignee: International Business Machines CorporationInventors: Devin A. Conley, Lakshminarayanan Krishnamurthy, Sridhar Sudarsan, Priscilla Santos Moraes

Patent number: 10877730Abstract: A method, system and computer-usable medium are disclosed for preserving temporal relevance of content within a corpus. A corpus is processed to generate temporally-relevant metadata and mined content, which in turn are processed to generate first temporal relevancy metrics. The cache history of a web browser is likewise processed to generate second temporal relevancy metrics, which in turn is processed with the first temporal relevancy metrics to generate first temporal relevancy scores. New documents are ingested into the corpus and existing documents are revised. Temporally-relevant metadata and mined content associated with the updated corpus are then processed to generate third temporal relevancy metrics. The second and third temporal relevancy metrics are then processed to generate second temporal relevancy scores, which is then used to provide a temporally-relevant response to a query.Type: GrantFiled: September 21, 2016Date of Patent: December 29, 2020Assignee: International Business Machines CorporationInventors: Sadanand R.

Patent number: 10838993Abstract: An approach is provided to receive, at a question answering (QA) system, a question and identify a politeness corresponding to a number of terms corresponding to the question that are included in a corpus of the QA system. The approach identifies the politeness of one or more terms included in each of a set of candidate answers responsive to the question. Finally, the approach scores each of the candidate answers, with the scoring being based, in part, on the politeness identified for each of the terms.Type: GrantFiled: January 3, 2017Date of Patent: November 17, 2020Assignee: International Business Machines CorporationInventors: Branimir K.
